`CAR-ROOF.

SPECIFICATION forming part of Letters Patent NO. 554,287, dated February I1, 1896.

Application filed May SI, 1895.

To all whom t may concern.'

Be it known that I, PETER II. MURPHY, a citizen of the United States, residing at the city of .East St. Louis, county of St. Clair, State of Illinois, have invented a certain new and useful Improvement in OareRoofs, of which the following is a full clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, wherein- ,Figure 1 is a top plan view.

Fig. 2 is a side `elevational view. Fig. 3 is a cross-sectional view showing one of the corner-caps in position. Fig. 4 is a similar view taken at the eave. Fig. 5 is a detail of the eave-hood clamp. Fig. 6 is a detail of the eave-clamp. Fig. 7 is a plan view of the corner-cap. Fig. S is a sectional View therethrough, taken on line 8 8, Fig. 7. Fig. 9 is a detail View of the joint between four roof-plates as covered by the corner-cap. Fig. l0 is a small detail view of an entire roof-plate.

This invention relates to a new and useful improvement in car-roofs of that class where the intersection of the standing seams of the sheets are covered by a corner-cap, the object being to so construct the sheets that they may be secured to the sheeting without puncturing them at any point for the passage of nails or screws.

)Vith this object in View the invention con- Y sists in the construction, arrangement, and

combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

In the drawings, A indicates the side walls of a car; B, the end plates; C, the facing; D, the crown-mold; E, the ridge; F, the purlins; G, the carlings, and H the sheeting, all of said parts being of any ordinary or approved construction.

My improved car-roof consists of a number of plates I, (see Fig. 10,) each plate being bounded on three of its sides or two sides and one end (the upper) with inverted U or V shaped flanges fi, il', and i", while the other side (the lower end) is preferably left plain and bent down, forming a small single-thickness flange fi", which fits in a groove in the crown-mold when the plates are in position.

I have said that each of the plates I are formed as above; but it will be understood Serial No. 551,273. (No `model.)

that it may be desirable to straighten (or omit) the double flange at the outer sides of the end plates in order that the plates may be turned down at the ends of the car, for obvious reasons.

The crown-mold is formed with a groove d along its upper outer edge, which receives the flange i" of the plates, as most clearly shown in Fig. 4.

Platcsl, as above described, are generally made duplicates of each other, and in being placed in position are laid on the sheeting on the oppositely-inclined sides of the roof, in order that they may be made to interlock.

As shown in Fig. 9, the flange i of plate `zu fits under flange if of plate x, while flange i" of plate '1U lits over the corresponding flange on plate y; lange t" of plate z ts over the corresponding flange of plate x, and flange i" of plate .e iits under flange t' of plate y, dac. This is not essential, however, as the plates may be laid in regular rows-that is, by laying one side complete and then laying the other, care being taken in this instance of starting at one end of the car and finishing at the other, otherwise there will remain a keyplate, which might prove objectionable in some cases. The plates being in position, it now remains to place the corner-caps and attach the running-board, also to secure the plates at the eaves. The corner-caps are indicated at J, and consist, preferably, of a fourway hood with intersecting channels in its under side. These channels are of greater width than the standing seams as made by the flanges t' t" and i before described, and

the purpose of this is to permit the plates toY have a slight play, due to the straining of the car and varying temperatureslwhich cause the plates to expand and contract. "Were the plates bound together by a tight joint, they could not move without buckling, and it is desirable that they be given some slight movement to prevent this and possible rupture of the joints and seams between them.

Cap J is perforated in its middle, through which perforation passes a bolt K, which bolt secures the running-board L in position. Bolt K passes through the running-board L, sleeper M, (which sleeper is grooved in its bottom to lit the cap J and standing seams,)

cap J, through the opening left at the joint of IOO the four plates I, sheeting ll, and ridge E, as shown in Fig. 3. This bolt binds these parts closely together, and in` order to prevent water finding a passage along the sides of the bolt packing is stuffed therearound and in the standing seams, as indicated by the dots in Fig. S. This packing preferably consists of waste mixed with paint, which when packed in position hardens around the bolt and makes a tight joint.

To secure the sheets I. at the eaves, I cover and protect the standing seam by a hoodclamp N, whose construction is illustrated in Fig. 5, while between the seams I arrange cave-clamps O, in the form of a short section of an angle-strip, or an inverted-L shape, as shown in Fig. (i. These clamps are secured to the crown-mold and have no direct or positive connection with the plates, their function being to prevent the plates from rising, and also to keep the flange 1"" in thc groove d of the crown-mold.

The advantages of a car-roof as above described are many. The plates and cornercaps are held in position at the ridge by bolts, which also secure the running-board in position. At the eaves the plates are held by clamps. Expansion and contraction are permitted, obviating buckling, and no nails or screws perforate the plates.

I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my invention may be made and substituted for those herein shown and described without in the least departing from the nature and principle of' my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. A car-roof, consisting of plates having inverted-U-shaped flanges on three of their sides, whereby the flanges of the plates when assembled engage each other at the ridge and side seams in such manner that the top and side flanges on said plates alternately overlap and underlap each other, locking the plates in position, substantially as described.

2. A car-roof consisting of' plates having inverted-U-shaped flanges on three of their sides, whereby the flanges of said plates, when assembled, engage each other at the ridge and side seams in such manner that the top and side flanges on said plates alternately overlap and underlap each other, locking the plates in position without the use of fastening at the ridge, and suitable fastenings for the plates at the eaves; substantially as described.

3. A car-roof consisting of plates having inverted-U-shapcd flanges on three of their sides, whereby the flanges of said plates, when assembled, engage each other at the ridge and side seams in such manner that the top flange of one plate overlaps the top flange of the opposite plate, the side flanges of the firstmentioned plate over and under lapping the side flanges of adjacent plates, the top flanges of said adjacent plates underlapping the top flanges oi' their opposites and under and over lapping the side flanges of adjacent plates, locking all of said plates in position; substantially as described.

4:. In a car-roof, thc combination with the sheeting, of roof-plates having inverted-U- shaped flanges on three of their sides which engage with each other, corner-caps for thc intersection of the ridge and side scams, walksleepers, a ridge-pole, and a bolt which passes through the walk-sleeper, corner-caps, intersection of the seams, sheeting and ridge-pole, substantially as described.

5. The combination with the sheeting, of the roof -plates having inverted-lJ-shaped flanges en three of their sides, a corner-cap having intersecting channels of larger dimension than. said flanges,- said corner-caps covering the intersection of the seams formed by theA engagement between the flanges, said caps and plates being capable of independent movement, a packing which is stuffed in the seams at their intersection and covered by the corner-caps, suitable means for securing the plates to the ridge, and clamps N and vO for securing the plates to the eaves g substantially as described.

G. The combination with the sheeting and ridge-pole, of roof-plates formed with inverted-U-shaped flanges on three of their sides which flanges are adapted to engage each other, corner-caps for the intersection of the seams at the ridge, a running-board, a bolt which passes down from the running-board through the corner-caps, sheeting and ridgepole for securing said sheets in position at the ridge, a downturned flange at the cave end of the plates, a crown-mold formed with grooves to receive said downturned flanges, hood-clamps which are secured to the crownmold and which extend over the cave end of the side seams, and clamps which are secured to the crown-mold and extend up over the plates between the hood-clamps; substantially as described. l

In testimony whereof I hereunto affix my signature, in presence of two witnesses, this 27th day of May, 1895.
